Ocean Current That Keeps Europe Warm Is Weakening Because of Climate Change (washingtonpost.com)

The Washington Post: The Atlantic Ocean circulation that carries warmth into the Northern Hemisphere's high latitudes is slowing down because of climate change, a team of scientists asserted Wednesday, suggesting one of the most feared consequences is already coming to pass (Editor's note: the link may be paywalled; alternative source). The Atlantic meridional overturning circulation has declined in strength by 15 percent since the mid-20th century to a "new record low," the scientists conclude in a peer-reviewed study published in the journal Nature. That's a decrease of 3 million cubic meters of water per second, the equivalent of nearly 15 Amazon rivers.

The AMOC brings warm water from the equator up toward the Atlantic's northern reaches and cold water back down through the deep ocean. The current is partly why Western Europe enjoys temperate weather, and meteorologists are linking changes in North Atlantic Ocean temperatures to recent summer heat waves. The circulation is also critical for fisheries off the U.S. Atlantic coast, a key part of New England's economy that have seen changes in recent years, with the cod fishery collapsing as lobster populations have boomed off the Maine coast.

  1. It's the middle of April by Anonymous Coward · · Score: 0, Troll

    and I'm getting about a foot of global warming deposited onto my driveway. Yup, this science is definitely settled.

      Climate is changing? Interesting.
      Please, let me know when it didn't?

      Personally, I'd rather we spent the $trillions on known, well-understood issues where we can see sizable concrete benefits that help billions of people, than waste it chasing ephemeral results in a situation where the error-bars overshadow the conclusions.

      But I'm sure I'm just a shill for Exxon, right?

  2. Who is paying Slashdot to promote this baloney? by Anonymous Coward · · Score: -1, Troll

    George Soros team paying Slashdot editors, keeping them in bling and blow.

    Claiming the ocean current is changing isa rather a big claim. And then to attribute it to "global warming" really takes a huge amount of hubris. Some grad student in "earth science" decided that his "feeling" should be taken as fact.

  3. This will hold for the first ten years of cooling by SuperKendall · · Score: -1, Troll

    Since we are entering a long term cooling trend again, I figure we'll see lots more stories like this over the next decade to explain why nations are getting colder again.

    About 20 years out, when the lid is truly off, they'll start dying down though sadly no-one will be punished for misleading everyone.

    About 50 years out, is when we'll all realize how freaked out we should have been by the next cooling cycle and will probably be desperately pumping CO2 into the atmosphere to try and head off the cooling cycle - but since of course co2 has no correlation to temperature it will sadly have no effect.

  4. Intelligence Design? by mi · · Score: -1, Troll

    That's one of them-there feedback mechanisms that cools the poles in the event they get too hot.

    In their quest to vindicate the Global Warming "theory", adherents are adopting ideas of Intelligent Design... Now that is as scientific as it gets...
